All of a sudden, overnight, the water in the rubbermade with my cured liverock, looks gross. The rock has been in there with two powerheads and a heater, for a full week now (no
skimmer). As of the day before yesterday,
Ammonia was still 0. Just got my light yesterday and got it hung last night , so after months of researching and purchasing equipment, I'm FINALLY ready to add water!! YAY!! I hate to put any of that water with the rock into the tank though. I'd prefer to start with all fresh water, but will there be any negatives regarding the cycle, if I do that? Last night, the powerheads were covered with a fine brown powdery film. I'd think it was too soon for a
diatom bloom signaling end of cycle but could it be that? I'll test for
ammonia,
nitrites and
nitrates tonight. So...should I just add all fresh
RO/DI water to my new tank rather than add any of this gross water?
Thanks.
